These results show that only single seizures cause activation of cytokine cascade and associated inflammatory signals. In the case of recurrent seizures, these signals may result in structural changes in the nervous tissue, which are generally associated with drug refractory epilepsy.

Despite high-dose intravenous immunoglobulin (IVIG) is widely used in treatment of a number of immune-mediated neurological diseases, the consensus on its optimal use is insufficient. To define the evidence-based optimal use of IVIG in neurology, the recent papers of high relevance were reviewed and consensus recommendations are given according to EFNS guidance regulations. The efficacy of IVIG has been proven in Guillain-Barre´syndrome (level A), chronic inflammatory demyelinating polyradiculoneuropathy (level A), multifocal mononeuropathy (level A), acute exacerbations of myasthenia gravis (MG) and short-term treatment of severe MG (level A recommendation), and some paraneoplastic neuropathies (level B). IVIG is recommended as a second-line treatment in combination with prednisone in dermatomyositis (level B) and treatment option in polymyositis (level C). IVIG should be considered as a second or third-line therapy in relapsing-remitting multiple sclerosis, if conventional immunomodulatory therapies are not tolerated (level B), and in relapses during pregnancy or post-partum period (good clinical practice point). IVIG seems to have a favourable effect also in paraneoplastic neurological diseases (level A), stiff-person syndrome (level A), some acute-demyelinating diseases and childhood refractory epilepsy (good practice point).

This study shows that i.v. haloperidol is very effective in relieving migraine-associated pain. Because the majority of the patients had taken other medication without response, haloperidol appears to be an effective rescue medication even when other types of treatment have failed. Relapses are rare, but side effects are common, limiting the use of haloperidol in some patients.
